如何将XML数据反序列化为从列表序列化的列表？

Question

I've serialized a bunch of records from a list to an XML file with the following code. This works very well, and I have a really nice XML file that stores my data when I close my program.

How do I now read that data back into my list when the program opens? I can't seem to figure out how to cycle through the records in the file and store them in my list of records.

    private void WriteXML()
    {
        try
        {
            System.Xml.Serialization.XmlSerializer XMLwriter = new System.Xml.Serialization.XmlSerializer(typeof(callsignRecord));

            System.IO.StreamWriter XMLfile = new System.IO.StreamWriter("Known Callsigns.xml");
            foreach (callsignRecord callsign in Callsigns)
            {
                XMLwriter.Serialize(XMLfile, callsign);
            }
            XMLfile.Close();
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
        }
    }

Below is as far as I got:

    private void ReadXML()
    {
        try
        {
            System.Xml.Serialization.XmlSerializer XMLreader = new System.Xml.Serialization.XmlSerializer(typeof(callsignRecord));

            System.IO.StreamReader XMLfile = new System.IO.StreamReader("Known Callsigns.xml");
            while(!XMLfile.EndOfStream)
            {
                // Okay, great I can Deseralize the file, but how do the records go from the file to the List with this?
                XMLreader.Deserialize(XMLfile);
            }
            XMLfile.Close();
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
        }
    }

For reference, the data stored in the XML file came from a list with the following format:

public class callsignRecord
{
    public string User { get; set; }
    public List<AliasRecord> AliasRecords;
}

public class AliasRecord
{
    public string Alias { get; set; }
    public string Number { get; set; }
}

I also tried serializing the whole list as an object instead of doing it record by record, but that didn't work to well either.

EDIT: The code shown below does work. The reason it failed when I tried it was I started by trying to deserialize a list that was serialized record by record. Clearly the two approaches aren't compatible the code below is the correct approach to this.

    private void WriteXML()
    {
        try
        {
            var XMLwriter = new XmlSerializer(typeof(List<callsignRecord>));

            System.IO.StreamWriter XMLfile = new System.IO.StreamWriter("Known Callsigns.xml");
            XMLwriter.Serialize(XMLfile, Callsigns);
            XMLfile.Close();
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
        }
    }

    private void ReadXML()
    {
        System.IO.StreamReader XMLfile;
        try
        {
            var XMLreader = new XmlSerializer(typeof(List<callsignRecord>));

            XMLfile = new System.IO.StreamReader("Known Callsigns.xml");
            Callsigns = (List<callsignRecord>)XMLreader.Deserialize(XMLfile);
            XMLfile.Close();
        }
        catch (Exception e)
        {
            MessageBox.Show(e.Message);
            //XMLfile.Close();
        }
    }

Can you try this

     // Create an instance of CallsignRecordclass.
     CallsignRecord serializeObject = new CallsignRecord();
     // Create an instance of new TextReader.
     TextReadertxtReader = new StreamReader(@”C:\Callsigns.xml”);
     // Create and instance of XmlSerializer class.
     XmlSerializerxmlSerializer = new XmlSerializer(typeof(CallsignRecord));
     // Deserialize from the StreamReader.
     serializeObject = (CallsignRecord)xmlSerializer.Deserialize(txtReader);
     // Close the stream reader
     txtReader.Close();
